rlhis invention relates to window sashes and particularly to what areknown as revolving 'sashes; and the object of the inven-` tion is toprovide an improved manner of supporting and guiding the sash frames inthe window frame and especially the supplemental sash bars which aremovable `with respect to the bead and parting `strips of the windowframe; a further object being to providethe .opposite sides of thesasheswith supplemental rails in connection with which the sashes` arepivotally supported and `to the provision of projecting flanges on saidsupplemental rails cooperating with the parting strip of the windowframe to form a pivotal mounting of said rails with respect tothe windowframe facilitating the free and easy action of the sashes in the frameand readily adjusting and fitting the sashes to the window frame; a`further object being to provide means on the upperand lower sashes forpreventing accidental opening of the sashes when in closed position; astill further object being to provide iiieanson` the pivots of saidsashes for .coupling the counterbalance weight chains orV cordstherewith; andwhith these and other objects in View, the inventionconsists in a window sash of the class and for thepurpose specied whichis simple in construction, eiiicient in use` and which is constructed ashereinafter described` and claimed. j i j `The invention is fullydisclosed in the following specitication, of which the accompanyingdrawings form a partin which the separate parts of my improvement aredesignated by suitable reference characters in each of the views, and inwhich .j Fig. 1 is aninside view of a window frame showing oneof thesashes in a partially open position.

Fig. 2 is a longitudinal, sectional view through the frame and sashesshown in Fig. 1.V Fig. 3 .is a transverse, sectional view through oneside of the window frame and through part of two Lof the sashesmountedtherein, showing the pivotal mounting of one sash. i Fig.` 4 is a viewsimilar to Fig. 3 indicatingone of the sashes in a swung position.

Fig. 5 is an end view of the central portion of one sash indicating themanner of attach- Ving the counterbalance chain therewith.

F ig. 6 is an enlarged, sectional and side View of the lower cornerportion of the bote' tom sash illustrating a latch device which Iemploy; and, Y j

Fig. 7 is a partial section on the line 7-7 of Fig. 1, showing a stopemployed in conneet-ion with the top sash.

In the drawings, I have indicated at 10 a window frame of any desiredform and construction. At 11, I have shown the lower sash; '12 the uppersash mounted to move vertically in the frame 10 in the usual channels orguideways formed by the inner and outer bead strips 13 and 14C and thecentral parting strip 15.

The sashes 10 and 11 may be composed of wood as illustrated in theaccompanying drawings or of any other desired construction commonlyknown in the art. The side rails of the upper and lower sashes includesupplemental rails 16 and 17 respectively. The Vrails 16 and 17, in theconstruction shown, are formed from sheet metal and are of channel,cross-sectional form,the crosshead of each rail having arrangedlongitudinally thereof an outwardly pressed arc-shaped bead 16a-17aseating in a corresponding groove .formed in the outer surfaces of theside rails of the sashes to normally key and retain theisashes againstswinging movement with respect to the rails. The central portions of thesasl-ies Yare pivoted to their respective rails by screws 18 secured tothe side rails of the sashes 11 and 12, and the heads 19 of which aredisposed in the chan nels of the rails 16 and 17. Mounted on the screwsadjacent the heads thereof are large washers or plates 20 Awhich forniseats for coil springs 21 which are disposed between said plates and thecrosshead of the rails, and normallyserve to vhold .the sashes intensional engagement with the rails as will be apparent. 9

It is also preferred that the washers or plates 20 include upwardlyextending hooks 22, `by means of which the chains or cords 23 ofcounterbalance weights may be attached to the' resepective saslies.`

ino

One side flange 24-24ta of each rail 16-17 respectively is arranged atright angles to the crosshead and adjacent the bead strips 13 and 14 asclearly seen in F ig. 3 of the drawings, said flange terminating shortof the base of the channel formed between the bead strips and partingstrip, whereas the other flanges 25, a, of the rails 16 and 17respectively are fashioned to form outwardly projecting beads 26-26awhich overlie the inner faces of the parting strip 15 to facilitate themounting and fitting of the sashes within the window frame and also toform of the corner portions 26?), note Fig. 7 pivots which can act uponthe corner portions 15a. of the parting strip 15 to permit slight,swinging movement of the rails 16 and 17 within and between the partingstrip and the outer beaded strips 13 and 14E in the operation ofswinging the window sashes upon the pivots and with references to therails 16 and 17, it being understood that the grooved portions of theside rails of the sash tensionally pass over the beads 16a-17a in thisoperation.

I also prefer to employ at the upper ends of the rails 17 and on theouter surfaces thereof, inwardly projecting stop lugs 27, which areformed from the material of the rail and operate in conjunction with theouter faces of the side rails of the sash 12 to limit outward swingingmovement of the upper end of said upper sash.

It will be understood that the upper sash may be swung into the positionshown in Fig. 2 of the drawings by exerting outward pressure on thelower portion of the upper sash; and this sash may be moved intovarious, anguiar positions to give the desired ventilation and also tofacilitate the cleaning of the window pane of the sash. The lower cornerportions of the lower sash 11 are each provided with latch or catchdevices in the form of a pin 28 adapted to pass into an aperture 29 atthe lower endof the rail 16, the pin being moved into operative andinoperative positions by a handle member 30 exposed on the inner face ofthe sash. Each of these devices is of similar construction, and thebrief description of one will apply to the other.

These catch devices are adapted to lock the lower sash against swingingmovement when in closed position, and by releasing these catch devices,the lower sash may be swung on its pivot in the rail 16 into differentangular positions with respect to the window frame for the purpose ofventilation and for the further purpose of cleaning the outer surface ofthe window panel.

It will be understood that the length of the supplement-al rails 16 and17 is equalto or substantially equal to the length of the side railsofthe sashes 11 and 12, and that said rails are movable in and between thebead strips and parting strips at opposite sides of the window frame inthe operation of raising -ment of the sashes on their pivots. It will beunderstood that while I have shown certain details of construction forcarrying my invention into effect, that I am not necessarily limited tothese details, and various changes in and modifications of theconstruction herein shown and described may be made within the scope ofthe appended claims without departing from the spirit of my invention orsacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a window frame construction, the combination with the upper andlower sashes and the conventional parting strips of the window frame, ofsupplemental rails guiding the sashes in their sliding movement withrespect to the frame and parting strips, means centrally of the sashesfor pivotally supporting the same in connection with said supplementalrails to permit swinging movement of the sashes in said rails in thedifferent positions of the rails with respect to said frame, and therails of each sash including outwardly projecting flange portions whichoverlie and are in constant engagement with the outer surface and edgesof the parting strips for providing pivotal mounting of said rails withrespect to the parting strips of the window frame.

2.
